Product Review – Juvederm Vollure XC

Friday, March 24th, 2017

 

With now over 25 synthetic injectable fillers available in the U.S., one would think there is little need for further filler products. But the ability to modify hyaluronic acid filler structures to create different aesthetic effects assures that more such filler products will continue to become available.

Juvederm Vollure XC Dr Barry Eppley IndianapolisJuvederm Vollure XC has just become FDA-approved for injection into moderate to deep facial wrinkles such as the nasolabial folds. It is formulated with proprietary Vycross technology, which blends different molecular weights of hyaluronic acid, contributing to the filler’s long duration. Juvederm Vollure XC will be available in the United States in April 2017. This specific filler is not new in other parts of the world as it was first approved in Europe under the name of Juvederm Volift in 2013.

In the clinical trial that led to its approval, 59% of patients saw improvement in moderate to severe nasolabial folds for up to 18 months, with 82% of patients saying they were very satisfied at 6 months and 68% at 18 months. With a duration that has been shown to last up to 18 months from the initial or touch-up injection in a majority of patients, this is the longest lasting result shown in a clinical study in the nasolabial folds to date.

Like all injectable fillers it has typical side effects such as swelling, tenderness, bruising, firmness lumps/bumps, redness, pain, discoloration, and itching. Other than lumps of the material these side effects resolved within one week after injection.

Product Review – Restylane ReFyne and Restylane DeFyne

Sunday, March 5th, 2017

 

With over 25 synthetic injectable fillers on the US market it can be argued that how may more do we really need. But each new injectable filler offers some advantage and thus there is room for more. These growing number of injectable fillers has led to the concept of a toolkit of injectable treatments that allows customized use for specific facial aging indications  and applications.

Restylane Refyne and Restylane Defyne Dr Barry Eppley IndianapolisThe most recently approved filler is Restylane Refyne and Restylane DeFyne.  These have been FDA approved for the treatment of nasolabial folds. The main difference with these Restylane products and other hyaluronic acid fillers in in their inherent flexibility due to the proprietary XpresHAn technology. (X = cross-linking, Pres = pressing gels through mesh for calibration, HA = hyaluronic acid) This allows facial expressions (smiling, frowning, etc) to not feel stiff and more natural due to the flexibility of the filler material.  While new to the U.S. the product has been used in Europe for years under the name of  Emervel.

Restylane Refyne is the most flexible and provides support for moderate lines while Restylane Defyne is less flexible and is intended to support deeper lines. Their advantage amongs injectable fillers is their ‘Natural Expression in Motion’. Most patients treated felt that their facial expressions were unaffected and the location of the filler was not detectable.

Clinic Snapshots – Jaw Angle Augmentation Fillers vs Implant

Monday, December 26th, 2016

 

Augmentation of the facial skeleton has historically been done through the placement of preformed implants. The past decade has seen the emergence of a variety of injectable materials to create soft tissue volume augmentation. These have included a large number of synthetic fillers as well as autologous fat. As their use has become more common and pervasive throughout aesthetic surgery, the injectable approach has been applied to every conceivable aesthetic facial need including augmentation of the bony cheeks, chin and jaw angles.

An injectable filler can be used for jaw angle augmentation. It does not usually produce the same result as a well selected jaw angle implant as it can not create angularity and sharper definition with the push of a soft material like fillers or fat. Thus injectable fillers for jaw angle augmentation is often done as a test or trial or are sometimes performed as a convenient opportunity at the time of other facial surgery using fat injections.

jaw-angle-implants-vs-injectable-fillers-dr-barry-eppley-indianapolisBut beyond that of a trial, the use of injectable fillers as a long-term method of jaw angle augmentation is compromised by economic issues. When one compares the volume of an injectable filler to an actual jaw angle implant (in this picture 1.5cc of Radiesse to a medium vertical lengthening jaw angle implant) the tremendous discrepancy in its volume/size can be seen. By comparing weights alone it can be seen that it would take more than 5cc to 7cc of a filler to match the volume created by an implant.

Because of their long-term cost issues, injectable fillers are a short-term approach to jaw angle augmentation. This is not only because they are not permanent but the sheer cost of trying to replicate an initial jaw angle implant effect.

Product Review: Allofill Injectable Filler

Saturday, October 8th, 2016

There have been numerous injectable fillers for facial use that have become commercially available since 2002 when the product concept was introduced. All of these fillers have been of the synthetic variety containing mainly resorbable and a few non-resorbable materials. While these are convenient off-the-shelf products, almost all only offer a temporary augmentation effect.

Fat grafting as become a popular form of facial voluminization as it offers the potential for better long-term augmentation. It achieves that effect as it is harvested from the patient and such autologous fat cells can potentially survive the transfer process. But it is a surgical procedure and not a ready made product.

allofillAllofill is the newest member of the off-the-shelf injectable filler products. While premade it differs because it is composed of fat…specifically cadaveric fat. Like many other alloplastic (cadaveric-derived) graft materials, this is a tissue bank-based material. It is derived from donated human adipose tissue intended for transplantation. Its biologic supposition is that, like naturally harvested fat, it provides a tissue scaffold/matrix which can become ingrown by blood vessels and fibroblasts to create new natural tissue. The difference is that natural fat has live adipocytes while Allofill does not.

In theory, Allofill offers the convenience of a premade injectable filler with the long-lasting results of fat grafting. The former is absolutely true, the latter awaits long-term clinical studies to substantiate. It is available in a 3cc syringe which is two to three more than all other injectable fillers.

Lower Blepharoplasty for Fat Injection Removal

Wednesday, September 7th, 2016

 

Treatment of tear trough and under eye hollows has been revolutionized by the use of injection materials. Using either resorbable injectable fillers or fat taken from the patient, injection under the eyes can fill out sunken areas creating a rejuvenated appearance. Although there are advocates for either synthetic fillers and fat, both materials can have good success in the lower periorbital region.

While many patients have good improvement in their tear troughs and under eye hollows with injections, not all patients do. The under eye area is the most technique sensitive area of the face for any type of injection. The thin tissues of the lower eyelid reveal any asymmetries and irregularities of the injected material. This may not be apparent for several days or weeks when any swelling has subsided. In some cases too much volume ends up creating the appearance of lower eyelid ‘bags’ which the patient is swelling and will go away on its own.

Solving these lower eyelid injection materials is fairly straightforward with hyaluronic-based injectable fillers. Enzymatic digestion with hyaluronidase injections can rapidly remove any excess material. But this is not the case with other types of injectable fillers (e.g. Radiesse) and fat injections for which no reversal injections exist.

lower-blepharoplasty-for-injected-fat-removal-dr-barry-eppley-indianapolislower-blepharoplasty-injected-fat-extraction-dr-barry-eppley-indianapolisSuch materials can only be removed by direct excision through an open eyelid approach. By exposing the deeper eyelid tissues under the skin any problematic material, such as fat, can be directly removed. Injected fat looks different than lower eyelid compartmental fat and is fairly easily identified by its linear horizontal orientation. It can be carefully lifted out from the tissues in which it is embedded.

For those patients so afflicted with undereye contour problems from injected fat or particulated synthetic fillers, excision is the only effective treatment. Like all lower blepharoplasty procedures the subciliary and lateral canthal incision usually heal in an inconspicuous fashion.

Jaw Angle Implants vs Injectable Fillers Volume Effects

Saturday, July 2nd, 2016

 

Jaw angle implants have become more recently recognized as an essential part of jawline augmentation. While much focus has historically been on the front protruding part of the jaw through chin augmentation, it is now recognized that the chin represents just a part of the total lower facial effect.

While jaw angle implants have been around for several decades they have been limited to an implant style that only provides width to the ramus of the mandible. While this has a beneficial role in some patients, many jaw angle deficiencies are as much vertical if not more so than just width. Lengthening the jaw angle and creating a more obvious angularity to the back part of the lower jaw has some major aesthetic benefits.  This has been remedied today with more vertical lengthening jaw angle implants. Injectable fillers have also been used to create this effect with variable success. But it is an accepted ‘trial’ method for some patients to determine if such changes would be perceived as beneficial.

When it comes to jaw angle augmentation does an injectable filler really create the same effect as an implant? And if it does how does it compare volumetrically?How does the volume of an injectable filler compared to the displacement effect caused by a solid implant? In other words, how much injectable filler does it take to create the same effect as that of an implant?

Comparing facial implants and injectable fillers is done using volumetric displacement. Based on the Archimedes principle of displacement, volume of displaced water would be equal to the volume of the implant. Using newer vertical lengthening jaw angle implants of its three available sizes, their weights in grams and volume displacement were as follows:

JAW ANGLE IMPLANTS

Small              3.65 grams     1.6 ml

Medium        7.54 grams     2.7 ml

Large            14.98 grams    4.2 ml

Jaw Angle Implants vs. Injectable Fillers Dr Barry Eppley IndianapolisThe volume displacement of all injectable fillers is on the syringe so the comparison to jaw angle implants can be directly done. It shows that a 1cc syringe of any of the hyaluronic acid-based fillers (e.g., Juvederm) would be equal to less than half of a small jaw angle implant. Larger jaw angle implants more directly compare to more than two to three 1.5cc syringes of Radiesse.

Volume alone, however, is not the complete story of any material’s external facial augmentation effect. Besides volume there is the issue of how well the material pushes on the overlying soft tissues to create their effect. This is known as G Prime Force or the elastic modulus. By feel it is obvious that implants are stiffer than any liquid material and would have a higher resistance to deformation. (thus creating more outward effect given a similar material volume) It is therefore probable that comparing volume displacements alone overestimates the effect of injectable fillers compared to implants.

Volume Comparison Between Nasal Implants and Injectable Fillers

Thursday, June 16th, 2016

 

Augmentation of the nose is a frequent element in many rhinoplasty procedures. While the use of locally harvested cartilage grafts works in may cases, more significant augmentations of the dorsum require different volume addition techniques. The choices for major dorsal augmentation rhinoplasty for Asian and African-American patients, for examples, is either that of a nasal implant or a rib cartilage graft. But any patient that needs more than a few millimeters of dorsal augmentation faces the same choices.

The emergence of injectable fillers has now allowed for a non-surgical rhinoplasty. The basic concept of a non-surgical rhinoplasty is that it can only add volume. Noses can become bigger with an injection technique but they can never become smaller. An injectable rhinoplasty can be used to trial what the augmented nose will look like but it will not be a permanent result. While there are some long lasting injectable fillers, placement of them into the nose carries some significant risk. But at the least injectable filler provides an instantaneous result and the opportunity for the patient to determine if this type of nasal enhancement is right for them.

Nasal implants offer a permanent method for dorsal nasal augmentation that does not require a harvest site. But it is an invasive procedure and requires the commitment to having a synthetic material in the nose. For this reason some patients may want tio have an injectable filler placed first.

An interesting questions is how does an injectable filler in the nose compared to a nasal implant? How does the volume of an injectable filler compared to the displacement effect caused by a solid implant?

Nasal Implants Dr Barry Eppley IndianapolisComparing facial implants and injectable fillers is done using volumetric displacement. Based on the Archimedes principle of displacement, volume of displaced water would equal to the volume of the implant. (provided that they sink in water and nasal implants do) Using the most commonly used style of nasal implants for total dorsal augymentation (Rizzo nasal implants from Implantech) of all available sizes, their weights in grams and volume displacement were as follows:

NASAL IMPLANTS

Extra Small    0.96 grams    .7 ml

Small             1.14 grams     .8 ml

Medium         1.37 grams    1.1ml

Large             1.71 grams    1.5ml

Extra Large   1.95 grams    1.7 ml

Nasal Implant vs Radiesse Filler Dr Barry Eppley IndianapolisThe volume displacement of all injectable fillers is on the syringe so the comparison to nasal implants can be directly compared. It shows that a 1cc syringe of any of the hyaluronic acid-based fillers (e.g., Juvederm) would be equal to small and medium sized styles of nasal implants. Larger nasal implants more directly compare to a 1.5cc syringe of Radiesse. (which weighs 1.7 grams)

Volume alone, however, is not the complete story of any material’s external facial augmentation effect. Besides volume there is the issue of how well the material pushes on the overlying soft tissues to create their effect. This is known as G Prime Force or the elastic modulus. By feel it is obvious that implants are stiffer than any liquid material and would have a higher resistance to deformation. (thus creating more outward effect given a similar material volume) It is therefore probable that comparing volume displacements alone overestimates the effect of injectable fillers compared to implants. This may be particularly relevant in the nose where the nasal skin is less elastic and more firmly attached than other facial areas.

The use of 1 to 1.5cc of an injectable filler can compare volumetrically to that of an implant in the nose for more significant dorsal augmentations.

Volume Comparison of Cheek Implants and Injectable Fillers

Wednesday, June 1st, 2016

Cheek augmentation is a common facial reshaping procedure that is done for both aesthetic enhancement and volume restoration due to aging. It is the one facial procedure that, while historically only done with cheek implants, is now done more often by injection methods using synthetic fillers or fat.

The emergence of injectable methods is now the most common approach for cheek augmentation. Any of the synthetic fillers can be used since the cheek is a broad area and is spread out over the cheekbone as well as below it in the submalar region.While no synthetic injectable filler provides a permanent result, it does provide an instantaneous result and the opportunity for the patient to determine if this type of facial enhancement is appealing to them.

Cheek implants offer the only guaranteed permanent method  for cheek augmentation. But this requires a surgical commitment to an invasive procedure and has certain risks and complications. Injectable fillers can also be placed over a broader surface area greater than that which most cheek implants can.

An interesting but relevant issue when using injectable fillers for cheek augmentation is how do they compare volumetrically to that of cheek implants. To create an injectable cheek augmentation effect, what volume of injectable filler is needed to compare to what a cheek implant does? An injectable method is only a fair test in facial augmentation if similar volumes of material are placed that compares to what an implant does.

It shows that a 1cc syringe of any of the hyaluronic acid-based fillers (e.g., Juvederm) would be equal to small and medium sized styles of cheek implants.ess than even a small chin implant. Larger cheek implants more directly compare to a 1.5cc syringe of Radiesse.

(thus creating more outward effect given a similar material volume) It is therefore probable that comparing volume displacements alone overestimates the effect of injectable fillers compared to implants.

The comparison between injectable fillers and implants in the cheeks may be different than in many other facial enhancement sites. Because the cheeks cover a significant soft tissue area not supported by bone the direct volumetric comparison may be more similar despite its lower elastic modulus.

Volume Comparison of Chin Implants and Injectable Fillers

Sunday, May 29th, 2016

 

Chin Implant Augmentation Indianapolis Dr Barry EppleyChin augmentation is a common aesthetic facial reshaping procedure that is second only to rhinoplasty. It has been traditionally performed by the placement of a preformed implant. While many different chin implant styles have been used over the years, the basic concept of an alloplastic chin augmentation is the same.

The emergence of injectable methods for facial augmentation using a variety of injectable fillers and fat has now become an accepted treatment approach for chin augmentation. While no injectable material offers an assured and permanent outcome as that of an implant for chin augmentation, it does provide an opportunity for patients to non-surgically ‘wear’ the result for awhile to determine if it suits them.

An interesting but relevant issue when using injectable fillers for chin augmentation is how do they compare volumetrically. To create an injectable chin augmentation effect, what volume of injectable filler is needed to compare to what a chin implant does? It is not a fair comparison if one is ‘testing’ an injectable filler and the volume injected does not equal what that of the effect that a chin implant does.

Volume Displacement of Facial Implants Dr Barry Eppley Indianapolisextended-anatomical-chin-implantComparing facial implants and injectable fillers is done using volumetric displacement. Based on the Archimedes principle of displacement, volume of displaced water would equal to the volume of the implant. (provided that they sink in water and all chin implants do) Using the most commonly used extended anatomic chin implants (Implantech) of small, medium, large and extra large, their weights in grams and volume displacement were as follows:

Small Chin Implant        2.1 grams     1.3cc

Medium Chin Implant   2.7 grams      1.7cc

Large Chin Implant      3.4 grams     2.2cc

X Large Chin Implant  4.0 grams     2.7cc

The volume displacement of all injectable fillers is on the syringe so the comparison to chin implants is straightforward. It shows that a 1cc syringe of any of the hyaluronic acid-based fillers (e.g., Juvederm) would be less than even a small chin implant. A small anatomic chin implant more favorably compares to 1.5cc of Radiesse. Larger chin augmentation effects requires up to 3ccs of injectable filler regardless of the type.

There are other variables that affect how any of these materials create an external facial augmentation effect. The most significant would be how well does the material push on the overlying soft tissues or push off of the bone to create their effect. This is known as G Prime Force or their elastic modulus. It is quite clear that implants are stiffer than any liquid material and would have a higher resistance to deformation. (thus creating more outward effect given a similar material volume) Therefore it is probable that comparing volume displacements alone overestimates the effect of injectable fillers compared to that of chin implants.

Product Review – Lip Augmentation with Juvederm Ultra XC

Wednesday, October 7th, 2015

 

Lip Augmentation Dr Barry Eppley IndianpolisLip augmentation is one of the most common and historic procedures for hyaluronic acid-based injectable fillers. It would surprise many then to find out that despite its popularity and common usage, few of these injectable fillers are actually FDA-approved for use in the lips. There are a variety of reasons for this lack of approval but safety and effectiveness are not among them.

On October 1, 2015 the US FDA has approved Juvederm Ultra XC for injection into the lips and perioral (mouth) area for aesthetic augmentation in adults. Juvederm Ultra XC and Juvederm Ultra Plus XC injectable fillers are already FDA-approved for injection for moderate to severe facial wrinkles and folds around the nose and mouth. (nasolabial folds) Juvederm Ultra XC is a well known modified form of hyaluronic acid with prolonged duration (up to a year) that has lidocaine in it to improve the comfort of the treatment.

juvderm ultra xc injectable filler, dr barry eppley indianapolisIn FDA trials of Juvederm Ultra XC for lip augmentation, almost 80% of patients had visible improvement in lip fullness three months after injection. A near similar percent, (78%) stated that they had persistent improvement in lip size one year after injection. The most common adverse effects for Juvederm Ultra XC injectable filler are the same as other hyaluronic acid gels such as temporary swelling, redness and lumps and bumps.

What is unique about Juvederm Ultra XC injectable filler is that it offers long-term retention of lip augmentation results. Many hyaluronic acid-based injectable fillers are used for lip augmentation but their results often last six months or less.
